Abstract :
A chemically modified air-bearing surface (ABS) was experimentally investigated. Its surface energy was lowered by bonding nonpolar lube to the surface using ultraviolet light. The altered surface was shown to decrease the van der Waals force and to have good flyability under a 10-nm flying height (FH).
